diatom bloom due to new tank or not enough flow?

Upgraded my 75 to a 125 about a week ago. Used 200lbs of rock between what I had and what came with the 125 I bought. Purchased all new sand (20lbs dry, 60lbs live). I used about 30 gallons of new water, waited a couple days and added my fish and corals. All levels are good just starting to get diatoms on my sandbed and on some rocks. Wanted some input if people though it was due to a little cycle or not enough flow. I have 2 rio return pumps that say 2630 LPH, a maxspect gyre 130 and a jaebo rw8 on a low setting. Some rocks have diatoms, some have little bubbles on them and some rocks don't have anything on them.

It's pretty typical with a new tank and should burn itself out over the course of several weeks. Increasing flow will help reduce it by making it more difficult for it to attach but it's just one of the many cycles a new tank will go through in route to maturity.

Just the joys of a new tank. I am enjoying it myself as we speak.

Yeah when I set my 75 up it didn't last to long. I figured since I used all the rock and water from water changes I had circulating that I would avoid the algae stages
